What role does transportation play in reducing carbon emissions and other pollution?

Transportation, the source of nearly a third of the United States’ greenhouse gas emissions, is the fast-growing source of carbon pollution globally.

In order to keep global temperatures below levels that are dangerous to humans, we must make a large-scale shift away from driving alone. Thankfully, even small changes, such as a modest increase in bicycling, can keep massive amounts of carbon out of the atmosphere.

If we can reduce the number of cars on the road and, more importantly, the number of total trips, then we can cut not only the carbon pollution threatening the climate, but also the particulate and ozone emissions that carry serious health consequences for communities living near major highways. More information.
